一、ｕｉ层处理：
#region 重新生成手机服务栏目列表xml
private void createmetonetree()
{
xmldoc_metone = new xmldocument();
new town.com.mobileservicetypecollection().getmetonetree(out ds);
//生成根节点
xmlelement treecontentelement = xmldoc_metone.createelement("newdataset");
xmldoc_metone.appendchild(treecontentelement);
//递归生成频道的xml文档
for(int j=0;j<ds.tables["tree"].rows.count;j++)
{
if(int32.parse(ds.tables["tree"].rows[j].itemarray[2].tostring()) == 0)
{
this.bulidxmltree(treecontentelement,j);
}
else
{
continue;
}
}
string filename = server.mappath("xml/metonetree.xml");
xmldoc_metone.save(filename);
}
#endregion
#region 构xml树

//生成tree节点
xmlelement treeelement = xmldoc_metone.createelement("tree");
tempxmlelement.appendchild(treeelement);
this.appendchildelement("metoneid",temprow.itemarray[0].tostring(),treeelement);

一点说明：感觉这些代码基本上都是自解释的，关键点都有注释，看看就明白的。
二、解析ｘｍｌ的ｘｓｌｔ
<?xml version="1.0" encoding="gb2312"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform">
<xsl:output method="xml" version="1.0" encoding="gb2312" indent="yes"/>
<xsl:template match="newdataset">
<xsl:apply-templates select="tree"></xsl:apply-templates>
</xsl:template>
<xsl:template match="tree">
<div ondragstart="return false" style="padding-left:20px;" >
<xsl:attribute name="onclick">selectedentity = <xsl:value-of select="metoneid" />;clickonentity(this);redirect(<xsl:value-of select="metoneurl" />);</xsl:attribute>
<xsl:attribute name="open">false</xsl:attribute>
<xsl:attribute name="id">
<xsl:value-of select="metoneid" />
</xsl:attribute>
<xsl:attribute name="style">
<xsl:if test="count(ancestor::node()) > 2">
display: none;
</xsl:if>
cursor: hand;
</xsl:attribute>
<table border="0" cellpadding="0" cellspacing="0" style="line-height:130%">
<tr>
<td >
<a href="{metoneurl}" target="main"><xsl:value-of select="metonename"></xsl:value-of></a>
</td>
</tr>
</table>
<xsl:apply-templates select="tree"></xsl:apply-templates>
</div>
</xsl:template>
</xsl:stylesheet>
三、一个小技巧：用ｊｓ把ｘｍｌ的数据用ｘｓｌｔ解析后填充到固定的ｈｔｍｌ块中，比如ｄｉｖ，调用代码：initadmin(metonetree.xml, submenu,metonetree.xslt)，ｊｓ代码如下：
var view;//中英文版本切换
var xmldoc;//msxml2.dom对象
var selectedentity;//选中接点id号
function initadmin(filename, divtree,xsltfile, expid)//初始化树状结构
{
var xsldoc;
var strxml;
var objxml;
var xmlhttp;
var xslproc;
var xsltemplate;
//alert(filename);
xmldoc = new activexobject("msxml2.domdocument");
xmldoc.async = false;
xsldoc = new activexobject("msxml2.freethreadeddomdocument");
xsldoc.async = false;
xmldoc.load("xml/"+filename);
xsldoc.load("xslt/"+xsltfile);
xsltemplate = new activexobject("msxml2.xsltemplate");
xsltemplate.stylesheet = xsldoc;
xslproc = xsltemplate.createprocessor();
xslproc.input = xmldoc;
xslproc.transform();
document.all[divtree].innerhtml = xslproc.output;
if(expid != null)
{
expandsome(document.all[expid]);
}
}
